I have changed the .nc to ngc with no success. Selecting "all files" in the dialogue box allows the file to load, but I still receiver the same message "nested comment found" when I attempt to run the machine.

For some reason LinuxCNC thinks that there is a comment within a comment in the file. I don't know why it considers that to be a problem, but you probably have a bracketed expression in a comment line with a ; at the beginning or something similar.

ArcEye's suggestion of inserting; " PROGRAM_EXTENSION = .nc , .NC" confuses me as I do not know exactly where to install it.

It goes in the INI file, in the section suggested in the documentation I posted a link to initially.

when i would get ..... the same message "nested comment found" when I attempt to run the machine.
i would look for (start( a message)) don't think you can have double parentheses. only (start)

I realized that it is poor etiquette and keeping with my poor programming practices ( I prefer not to do it this way ) I deleted the first 3 or 4 lines in the .nc file and the program ran. ?????????????

I wish that I knew what I was doing.

Please advise


Unfortunately, unless you post the file , or at least the start of it, we cannot assist you.

The output from CAM programs is often poor, no 'punctuation' or spacing etc. which makes it quite hard to read.

I was always taught that you should never mix comments with code.
If that were adhered to, the interpreter could just ignore any line with a ; or ( character, which would make life a lot simpler for all.

Nothing attached - try changing the extension to .txt, it will allow anything with that extension

Comment within a comment.
I have no idea why that is considered to be a problem.
Change that to say

And I suspect that it will run fine.

The only other thing to be aware of is that CamBam is terminating the program with M30 rather than M2.

In some controllers this simply means stop and rewind, but it is subtly different with Linuxcnc
linuxcnc.org/docs/2.5/html/gcode/m-code.html#sec:M2-M30

Probably won't make any difference just be aware of it

Andy, ArchEye

Many thanks for all your input. Andy hit the nail on the head with the advice of changing the deleting the ( ) 's
